Abstract: 805,703. Magnetic compositions. OWENSCORNING FIBERGLAS CORPORATION. Feb. 3, 1956 [Feb. 3, 1955], No. 3416/56. Class 38 (2). [Also in Groups II and XXIII] Metal-coated glass flakes suitable for incorporation into metal melts for improving their mechanical or magnetic properties are made by flowing molten glass from a supply in the form of a hollow tube, coating the tube with a metal composition (which may be a metal, alloy, or metal compound), flattening the tube to form a laminated strip, and fragmenting the strip. As shown, molten glass leaves tank 10 through a horizontal annular orifice 14 and while still molten is collapsed to a double ribbon by driven rollers 18. The glass is coated with a metal composition on the exterior by sprays such as 20, 21 and 22, and the interior may be coated by passing the composition as a vapour, liquid or powder through one of the pipes 12 and 13; pipe 12 is shown provided with a spray head 15 for this purpose. The tube may be prevented from collapsing by supplying gas or vapour under controlled pressure through one of pipes 12, 13, or the decomposition of a metal compound such as lead tetraethyl, or a hydride or carboxyl, may provide the necessary vapour pressure. If a powdered metal is introduced into the tube a carrier such as a wax or oil may be used, or a low-melting metal may be fed down pipe 13 in the form of a solid rod melted by the heat of the glass at the nip between rolls 18. The glass may be coated with a composition such as a metal oxide or salt facilitating the subsequent bonding with a metal coating on the metal of a melt into which the plates are to be introduced. Suitable coating metals are stated to be Pb, Zn, Ni, Fe, Co, Mo, W, A1, Ti, Woods metal, Mg, Cu, Ag, Sb, Cd, cadmium-lead alloys, and tinindium (50 per cent of each). Hydrophobic compounds may be used in addition to the metal compositions to reduce water-vapour and other adsorption; numerous examples are given. Roll applicators 23 delivering the coating material from heated pans 24 may be used in addition to or instead of the above-mentioned coating methods; subsequent heat treatment of the coated strip may also be effected.
